Wire rope stretching assembling system with centering and aligning functions and assembling method thereof

Abstract

The invention discloses a wire rope stretching assembling system with centering and aligning functions and an assembling method thereof. The wire rope stretching assembling system comprises a stretching combination beam, a stretching traction system, an adjustable supporting seat and adjusting screws. The assembling method comprises the following steps that preparation is conducted, stretching traction rope upper anchorage devices are assembled to wire rope stretching end supporting seat lug plates and wire rope initiation end supporting seat lug plates; stretching traction rope bundles are assembled to stretching traction rope lower anchorage devices, stretching traction rope guide plates, and stretching traction piecing jacks; the stretching traction rope upper anchorage devices and thestretching traction rope lower anchorage devices are connected; a stretching beam on one side is laid; the stretching traction rope bundles, wire ropes, fixing wire rope initiation end lug plates arelaid; a stretching bam on the other side is laid and fixed; the stretching traction rope guide plates and the stretching traction piecing jacks are fixed; the adjusting supporting seat is assembled, primary aligning and vertical limiting are conducted; stretching and deviation measuring are conducted; supporting seat compressing plates are disassembled; and position is centered, and assembling anddisassembling are completed.

Description

technical field [0001] The invention belongs to the technical field of application of new high-strength steel materials, and in particular relates to a steel cable tensioning assembly system with a centering and alignment function and an assembly method thereof. Background technique [0002] The prestressed steel cable material has excellent tensile bearing capacity and belongs to the category of high-strength steel. Through the combined application with steel structures, it can give full play to the mechanical properties of steel and steel cables, provide new materials and new technology guarantees for the design of long-span structures and cantilever structures, and conform to the green construction concept of saving resources. Most of the large-diameter steel cables are designed to be connected by lug plates with pins at both ends, and it is necessary to apply a set prestress to the steel cables during the assembly and construction process in order to fully realize the de...

AI Technical Summary

Problems solved by technology

In the process of assembly and fixing, a large internal force is generated due to the tension of the steel cable, which leads to difficulties in the accurate assembly process of the lug plate at the tension end of the steel cable and the lug plate of the support end of the steel cable tension.

At present, chain hoists, jacks, or hammers are usually used to adjust the forced displacement of the short sheath of the
